Friday will be another hot day with nothing but clear sunny skies to start the day. Temps will stay in the low 90s inland.

The weekend will see a slight cooling with temperatures falling by 10 to 20 degrees on Sunday.

We actually have a chance of shower activity at the beginning of next week.

The heat has lead to Red Flag fire warnings. Crews were able to hold the line against two wind-whipped wildfires in the North Bay, but one in Tehama County continued to grow.

The Panther Fire north of the town of Butte Meadows had spread to 1,700 acres with no containment by Thursday morning. The fire is burning in a very remote area of brush and timber and is not threatening any homes, said state fire spokesman Daniel Berlant.

A fire in Sonoma County that has burned 125 acres did not grow overnight. Full containment on the Yellow Fire is expected later Thursday, Berlant said. "The continued wind throughout much of the north state is going to help fan these fires," he said. The Silverado Fire in Napa County has also been fully contained.
